Vented container

: R. R. LUBEN VENTED CONTAINER Filed Sept. 17, 1936 Patented Aug. 31, 1937 UNITED STATES PATENT OFFICE Claims.

This invention relates to containers or vessels provided with a pouring spout, and which because they are normally fluid tight when closed, makes it desirable to provide for venting the 5 interior of the container to the atmosphere when pouring the contents, to avoid the formation of an air look.

A primary object of the invention is to provide a container or vessel including a pouring spout 1() having a strainer at its inner end and an air venting tube passing through a portion of the strainer, while the opposite ends thereof are respectively located adjacent the mouth of the pouring spout and an upper portion of the vessel to provide for the ingress of air while the contents are being discharged.

A further object of the invention is to provide a simple and practical construction which may be utilized not only in connection with containers or vessels such as cocktail shakers and the like, but which may also be applied to a cap or cover for a container or vessel, such, for example as a container having a body of glass or other material and wherein the cap or cover is normally detachable from the body of the vessel.

With the above and other objects in view which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangements of parts hereinafter more fully described, illustrated and claimed.

A preferred and practical embodiment of the invention is shown in the accompanying drawing in which:-

Figure 1 is a vertical cross sectional view of a portion of a container having the present improvements applied thereto.

Figure 2 is a vertical cross sectional view of a modified form of vessel also showing the present improvements applied thereto.

Similar reference characters designate corresponding parts throughout the several figures of the drawing.

According to the embodiment of the invention shown in Fig. 1 of the drawing the same includes in its organization a container or vessel comprising a body A having an open top formed by a relatively constricted portion B which may be covered and uncovered by a suitable cover or lid C. The breast of the body A is provided with a laterally and substantially upwardly projecting pouring spout S whose outer end is exteriorly threaded as at l to receive a closure cap 2 while the end of the spout adjacent the body A is pro 55 vided with a strainer 3.

As shown in the drawing the vessel or container is equipped with an air venting tube 5. This tube has its outer end 5a terminating substantially at the mouth of the spout S while its other end 5b terminates substantially in the plane 5 of the edge of the neck portion B of the container. The intermediate portion of the tube 5 passes through a portion of the strainer 3 to which it may be attached by solder or other convenient means of attachment. The arm of the air venting tube 5 which passes through the spout S lies adjacent the upper edge of the pouring spout S so as not to interfere with the passage or flow of the contents through the spout when the cap 2 of the spout is removed. When the container or vessel A is in use, itiis customary to have the cover C in place as well as the cap 2 fitted to the spout; In that way the contents of the vessel may be agitated or shaken without splashing out, and, when it is desired to remove or pour the contents the cap 2 is removed from the spout S but the cover C is left in place, the same being fluid tight with respect to the body so as to prevent leakage of fluid when the container is tilted. As the contents are poured through the spout S, air will pass through the tube 5 and enter the interior of the vessel so as to permit relatively free flow through the spout. The presence of the tube 5 at the location of the strainer has the advantage that if the contents contain fruit pulp or other matter tending normally to clog the strainer when the contents are being poured, said tube will insure the ingress of suflicient air into the body to permit the head pressure of the contents forcing its way through the strainer due to the fact that ample provision is made for preventing an air look within the vessel, or, in other words, atmospheric pressure within the vessel may be balanced to that on the outside and permit the liquid contents of the container to force or wash the relatively small pieces of fruit pulp or the like through the strainer, thereby avoiding impedance to flow to any substantial extent,

Figure 2 of the drawing illustrates a modification of the invention wherein the vessel or container A is provided with a removable cover C provided with a lower body embracing edge 6 while the upper portion is of substantially dome shape and is preferably provided with an oblique edge wall 1 which terminates in a relatively flat top wall 8. The oblique wall 1 of the cover 0' carries a pouring spout S whose outer end is externally threaded to receive a detachable cap 9 while the inner end thereof is provided with a strainer l0 formed in the wall I. An air venting tube H is supported at its medial portion in the strainer I6 While the outer end thereof opens at the mouth of the spout S and the inner end opens into the space provided by the oblique Wall 1 of the cover. In this instance the tube H not only passes through the strainer IE but may be secured to the inside surface of the cover by solder I2 or its equivalent thereby securely holding the entire tube in place by reason of it being supported at tWo places, namely at the strainer and on the cover. This arrangement is desirable because it reduces the likelihood of displacement of the tube when the cover C is detached from the body and Washed or cleansed after using.

From the foregoing it will be apparent that a distinctive feature of the invention is that it proposes the use of an air venting tube passing through the spout of the vessel Where it is nor mally concealed as Well as out of the Way, and moreover passes through the strainer at one end of the spout so that the ingress of air is assured when the strainer is performing its intended function.

I claim:-

1. A cover for shaker type beverage dispensing containers including a body having a skirt adapted to fit the top of the container and the top of the body having a beveled portion, a pouring spout having its inner end secured to the said beveled portion, a strainer at the inner end of the spout and a vent tube having its intermediate portion passing the strainer while one end opens at the mouth of the spout and the other opens into the cover, said latter end being secured to the inside of the beveled portion of the cover.

2. A shaker type beverage dispenser comprising a normally air tight vessel including a removable cover, a pouring spout for the vessel, a removable cap for the outer end of the spout, a strainer at the inner end of the spout, and an air venting tube having its intermediate portion passing through the strainer while its outer end terminates substantially at the mouth of the spout and. its inner end opens into the said removable cover.

3. A shaker type beverage dispenser comprising a body having an open top adapted to be closed by a removable cover, a spout on the body, and an air venting tube carried by the body, said'tube having one end terminating at the mouth of the spout, and also having its opposite end terminating substantially at the edge of the open top and opening into said removable cover.

4. A shaker type beverage dispenser comprising a body having an open top adapted to be closed by a removable cover, a spout on the body, a strainer on the body at the inner end of the spout, and an air vent tube passing through a portion of the said strainer, said tube having one end terminating at the mouth of the spout and also having its opposite end terminating substantially at the edge of the open top and opening into the removable cover.

5. A shaker type beverage dispenser comprising a body open at the top, a cover therefor, a spout carried by the cover, a strainer on the cover at the inner end of the spout, an. air venting tube having its intermediate portion passing through the strainer While one end thereof terminates substantially at the mouth of the spout and the other end thereof opens into the cover.
